HEPA Filter Longetivity Spray Test

Posted August 9, 2010byadmin

Sentry Air Systems has performed multiple efficiency tests over the years. In this particular study, we tested the efficiency of our HEPA filter in a Sentry Air Ductless Spray Hood while spraying Colorplace Interior/Exterior Fast Dry Spray Paint. Overall, 40 cans (400 oz.) were sprayed.

3 Standard Filters were loaded into the Spray Hood:

The Sentry Air HEPA Filter [up to 99.97% efficient on particles 0.3 microns and larger]

The Pre-filter Pad

The Spray Pad

To determine the longevity of the HEPA filter, the airflow was measured throughout the test.
